FYI Ultimate Edition 2.9 and 4000 series have issues in live mode.
Simple fix, install in safe graphics mode, then load to safe graphics mode.
Install cat 11.2 or 11.3 or use my little tweakage to use 11.4b with 11.3 control file.
More to do with kernel and lack of support, so a kernel update is HIGHLY recommended.

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38.3-natty/ remember BOTH header packs with the image. Pre patched and ready to rock.
Only Cat 11.4b work with 2.6.38 kernel sets, so follow the tutorial.
